According to The State of World Fisheries and Aquaculture report (FAO, 2012) more than 80% of the commercial fish stocks are either over- or fully exploited. Marine capture fisheries are stagnant or declining since more than a decade and fisheries are also facing economic challenges such as a rising price of oil.
Do marine capture fisheries have a future in their present form? If not, what has to change in order to still be able to extract fish from the ocean's in some decades?
This is a very general question so I'm happy about answers considering a global context. For sure somewhere there is this one fishery that is perfectly environmentally friendly, does not use fossil resources and feeds this couple of handful of people in a place no one has ever heard of.
